I have a very large table [MasterFinal] and it includes a column that has a datetime type named CallDate
There is also a Calltime field so I would like to Alter the CallDate to type Date like 01/01/2011
Can someone help me?

CallDate is already datetime! you want to remove time part?
do you want to convert it to date only? and put time part into Calltime?
do you have values in CallTime now? or is it empty...

\can you give a sample and tell us what are you trying to do here...

I don't want to involve the Time column.
I was looking for a data type to cut the Datetime field down.
Is there a way to Alter Column?

here is the steps:

create table dt(
a int,
b datetime,
c time)

insert into dt(a,b) values (1,getdate()-0.745)
insert into dt(a,b) values (2,getdate()-0.123)
insert into dt(a,b) values (3,getdate()-0.445)

select * from dt

a      b      c
1      2011-02-17 03:24:27.230      NULL
2      2011-02-17 18:20:08.030      NULL
3      2011-02-17 10:36:27.230      NULL

update dt set c=b

select * from dt

a      b      c
1      2011-02-17 03:24:27.230      03:24:27.2300000
2      2011-02-17 18:20:08.030      18:20:08.0300000
3      2011-02-17 10:36:27.230      10:36:27.2300000

alter table dt alter column b date

select * from dt

a      b      c
1      2011-02-17      03:24:27.2300000
2      2011-02-17      18:20:08.0300000
